ABSTRACT:
Dual headed catheter assemblies are provided with a tubular central instrument body portion connected at each end to an elongate tubular distal body, each of which may be provided with an expansible balloon for dilatation purposes. One or more releasible connectors may be provided for sealingly connecting each of the tubular distal bodies to the central instrument body portion to allow for replacement of the tubular distal body and to simplify potential resterilization and reuse of the central instrument body portion. Alternative embodiments include multiple inflation lumens each provided with an individual inflation port which may be preferentially accessed by a fluid conducting inflation assembly configured to preferentially access individual inflation ports. The dual headed catheter with replaceable components may be utilized in place of multiple single headed catheters to perform medical procedures involving repeat access to vascular target sites.
